Mechanism analysis and improved model for stick-slip friction behavior considering stress distribution variation of interface
文献摘要：
Studying the evolution of interface contact state,revealing the"black box"behavior in interface friction and estab-lishing a more accurate friction model are of great significance to improve the prediction accuracy of mechanical system performance.Based on the principle of total reflection,a visual analysis technology of interface contact behavior is pro-posed.Considering the dynamic variation of stress distribution in interface contact,we analyze the nonlinear characteristics of contact parameters in different stages of stick-slip process using the above-mentioned experimental technology.Then,we find that the tangential stiffness of the interface is not a fixed value during the stick-slip process and the stress distribution variation is one of the important factors affecting the tangential stiffness of interface.Based on the previous experimental re-sults,we present an improved stick-slip friction model,considering the change of tangential stiffness and friction coefficient caused by the stress distribution variation.This improved model can characterize the variation characteristics of contact parameters in different stages of stick-slip process,whose simulation results are in good agreement with the experimental data.This research may be valuable for improving the prediction accuracy of mechanical system performance.
